FORCE- PUMP.

JlJECJFCATION forming part of Letters Patent No. 326,891, dated September 22, 1885.

(No model.)

To all whom it may concern;

Be it known that I, JAMES I. TURNER, a citizen of the United States, and a resident of Osseo, in the county of Hillsdale and State of Michigan, haveinvented certain new and useful Improvements in Force-Pumps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, which form a part ol' this speciiication, and in which- Figure l is a Vertical sectional View of my improved combined lift and force pump. Fig. 2 is a similar view of a slight modification of the same. Fig. 3 is a sectional view, on an enlarged scale, of the force-pump piston. Fig. 4 is atop view of the same. Fig. 5 is a bottorn view of the piston. Fig. (i is a bottom View of the lift-pump piston, and Fig. is a horizontal section on line .r x, Fig. l.

Similar letters of reference indicate corresponding parts in all the figures.

Myinvention has relation to combined force and lift pumps; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the pump barrel or cylinder, which is provided at its lower end with a bottom cap, B, formed into a socket, C, at its under side, into which the suction-pipe D is secured, and the upper side of the bottom cap is formed with an annular' groove, Irl, which forms a raised rim, F, around the central inlet-aperture in the cap, upon which rim the inletvalve G rests and plays.

An upper cap, H, tits upon the upper' end of the cylinder. and has a central aperture, I, for the passage of the piston-rod, an annular flange, J, projecting downward and provided with an inner cylinder, K, secured at its upper end to the said flange, and the cap is furthermore provided with an outlet-aperture, L, into which the discharge-pipe M is secured, a larger aperture, N, diametrically opposite to the discharge-pipe, which aperture N opens into a cylindrical air-chamber, O,

extending from the upper side of the cap, to which it is secured, to the base of the frame at the top of the well.

Two diametrically-opposite waste-apertures, P P, extend from the central aperture in the cap to the outer side ot' the same.

A frame, Q, is provided at the top of the well, and the discharge-pipe is at that point provided with a spout, and the piston-rod R provided with a handle, S, fulcrunied in the frame, and the said piston-rod passes down through a cap, T, secured at the upper end ot' a tube, U, which extends from the central aperture in the ca p ot' the cylinder to and through the upper end ofthe cylindrical airchamber, the upper end of which is closed, while its lower end is screwed into a socket, V, formed upon the top ot' the cylinder-cap.

The lift-piston NV is secured upon the lower end of the piston-rod, and consists of two disks, X X, having a number of radiating` apertures, Y, corresponding and registering with each other, between which disks the annular upwardly-bent leather packing Z is secured, and a disk, A', of leather or similar tlexible material, is secured at its center to the pistonrod above the piston, forming avalve playing upon the apcrtured piston.

A force-piston, B, is secured to the pistonrod playing in the inner cylinder, K, which projects down through about one-half of the length of thecylinder; and it will thus be seen that the lift-piston will draw the water into the cylinder through the suction-pipe, and after allowing it on the next downstroke to pass through its upwardly-opening valve the lift-piston will lift the waterin the dischargepipe, and on the downstroke the force-piston will force the water, which during the preceding upstroke has been drawn into the inner cylinder, up through the discharge-pipe, the pump in this manner operating and discharging at both strokes, making a continuous flow, which is aided by means of the cylindrical air-chamber, which will add regularity and even ness to the flow of water.

The force-piston is preferably constructed of an upper perforated disk, U, secured upon the piston-rod, a lower perforated disk, D', having an annular upwardly-proj ecting flange,

IOO

E', and the downwardly-bent packing-flangeV I3" is clamped between the edge of the upper disk and the fiange of the lower disk.

A disk, G, of leather, rubber, or similar material, is secured at its center upon the piston-rod in the space formed between the upper perforated disk and the lower flanged and perforated disk, being separated from the said disks by means of washers H; and the said iiexible disk will, when the piston is reciprocated, bear against the under side of the upper disk and cover the apertures in the same, while when the piston is at rest the disk will recede from the said apertures and allow Vany water accumulated above the piston to pass through the piston into the lower end of the pump, thus preventing the water collected above the said piston from freezing and obstructing the pump.

When the piston is in its upper position,the water which may have collected above the piston will also be discharged through the waste-apertures in the cap, so that no water can remain above the force-piston when the pump is not used, rendering the pump safe from being obstructed by frost.

It follows that any other form of lift-piston may be used; also, that the flexible disk or Valve in the force-piston may be substituted by a disk sliding upon the piston-rod below the upper perforated disk; that the lower perforated disk in this piston may be dispensed with, orihe apertures in the piston be simply provided with downwardly-opening valves,without departing from the spirit of my invention. It also follows that the force-piston may be of the usual construction without the discharge apertures, and that the piston, as herein described,may be used in other force-pumps; and I wish to reserve myself all rights of changes and modifications which may be made without departure from the spil it and intent of my invention.

In the modification shown in Fig. 2 the larger cylinder is divided, and the two halves of the cylinder may be connected by apipe of any desired length, the lift-piston reciprocating in the lower half, while the force-piston reciprocates in the smaller cylinder in the upper half, this construction being particularly desirable for deep wells, 'where the suctionpipe would be required to be too long to ren- .der the pump operativeif the pump-cylinder should bc placed within a distance from the Surface of the ground at which the piston-rod might be operated without requiring bracing, which would produce additional friction.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a force-pump, the combination, with an outer and anl inner cylinder below and an airchamber and discharge-pipe above a suitable apertured connecting cap, said cylinders, pipes, and cap being connected, as described and shown, of a common piston-rod provided with a lifting-piston secured to the end of said i rod and a force-piston in the said inner cylinder, consisting of a iianged perforated disk, and a flat perforated disk, an annular flanged packing secured between said disks, and a tlexible disk secured between two washers between said anged and flat disks, substan tially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

JAMES I. TURNER.
